Male Biological Clock

Interesting story today in the NY Times about men probably having a biological clock too. Except this one makes sperm more unhealthy, and the probability of birth defects rise. One highlight is a study on autism.
A recent study on autism attracted attention because of its striking findings about a perplexing disorder. Researchers analyzed a large Israeli military database to determine whether there was a correlation between paternal age and the incidence of autism and related disorders. It found that children of men who became a father at 40 or older were 5.75 times as likely to have an autism disorder as those whose fathers were younger than 30.
